Origin and Development of NFPA 17A
The Dry Chemical Extinguishing Systems Committee was activated in 1952. On April 6, 1983, the
Standards Council received a request to assign the subject of wet chemical extinguishing systems to the
appropriate committee. Listed systems had been available for some time. After the Foam Committee
declined the request, the Dry Chemical Committee was asked to assume responsibility for the project. In
May 1983, the Dry Chemical Extinguishing Systems Committee voted to accept the assignment and
requested that the Standards Council expand the Committee Scope to include the new topic. The
Committee also requested that the new document be identified as NFPA 17A, Standard for Wet Chemical
Extinguishing Systems. A subcommittee met in June 1983 to develop the text. In November 1984, the
Council approved a request to change the name of the Committee to the Committee on Dry and Wet
Chemical Extinguishing Systems. The 1990 edition was a partial revision of the 1986 edition.
The 1998 edition of this standard has been revised to clarify the requirements for protection of unclosable
openings and equipment shutdown.
